Abstract
The integral photography and deconvolution techniques have been applied to identify the three-dimensional (3D) positions of particles levitating in plasma. Artifacts in the light field, i.e. ghost particles, are removed by collating between results of integral photography and direct Richardson-Lucy deconvolution (RLD). Our reconstruction system is tested with known target particles and it is found that it works well in the range of our dust experiment. By applying the integral photography and RLD techniques to the obtained experimental image, we identified the 3D positions of dust particles floating in a radio-frequency plasma. Ghost particles are eliminated from the results by deconvolution and we succeeded in obtaining the 3D structure of a dusty plasma from a single-exposure image obtained from one view port.
